Elf: the Second Generation of Rich People Started by Beating up the Promise

[System + rich second generation + invincible + dragon family + parents and kings + no human heroine] Traveling across the Blue Star, I encounter Arceus, Wujitina and the Great God of Glory, who are about to go to war. Will time travel end? No, no, no, with the system in hand, you can get the strongest Mewtwo at the beginning, and beat him to the limit! Later, he was reincarnated into the Dragon Family of the Celestial Dragon Kingdom and became the useless young master of the strongest family. He originally wanted to eat and wait for death, but he could only work hard to resist the Arceus devouring plan of the two bosses. Many years later, when the leader of the dark organization who thought he controlled the Great God of Glory, Wuji Dina and many legendary elves blew the Flute of Heaven, little did he know that Long Yu had been waiting for a long time in the beginning. [If Elf counts as a heroine, she is not a single heroine] This book is considered half an invincibility novel, because the protagonist faces the final boss from the beginning, and the invincibility is not obvious, so the protagonist still needs to become stronger as a trainer and master the power that only trainers know.
